Cascading factor (C0473/1 and C0533)
This function is valid only if the configuration is not changed.
The following constants for the master frequency input (X9) can be set under C0425:
l 16384 inc/rev.
l 8192 inc/rev.
l 4096 inc/rev.
l 2048 inc/rev.
l 1024 inc/rev.
l 512 inc/rev.
l 256 inc/rev.
Cascading factors which cannot be raised to the power of two can be assigned via C0473/1 and
C0533. The following connection applies:
The quotient is limited to a maximum of ±32767.
Setting range of factors:
l C0473/1: −32767 ... +32767
l C0533: +1 ... +32767
Setpoint conditioning of the slave
The value read from X9, evaluated with C0425, C0473/1 and C0533, is the setpoint (speed and phase)
for the internal control and also the output value at the master frequency output X10.
The setpoint for the corresponding drive can be evaluated via the gearbox factor C0032 and C0033.
The direction of rotation of the corresponding slave can be set via the evaluation factors.
Differences compared to the speed control:
l As standard, there is no setpoint path in the setpoint integrator
l Change to the JOG value is not possible
l The additional setpoint is not active
Feedback system (X7)
Only the resolver can be selected as feedback system.
QSP at the slave
If you set QSP at the slave drive, the setpoint (C0050) is decelerated along the QSP ramp. Home
positions get lost. A driftfree standstill is obtained since the set phase is led by the QSP integrator
when switching QSP.
If the deceleration ramp is very short and can only be obtained with I
max
, the phase synchronism gets
lost (e.g. too high centrifugal mass for the set deceleration ramp).
The setpoint for the following slave(s) is continued to be output at the master frequency output.
CINH at the slave
If a slave drive is inhibited, the motor is coasting at the friction torque. The master frequency output,
however, continues to output the setpoint for the following slave. If the slave is enabled again, the
drive accelerates to its setpoint (possibly at the current limit):
The phase difference is set to zero when switching CINH. Home positions get lost.
